In preparation for a potential Iranian attack on Israel, the U.S. deploys additional troops and weapons to the Middle East.

• A guided missile submarine and a carrier strike group with F-35C fighter jets have been dispatched to the Middle East by the Pentagon.
• The U.S. military is increasing its presence in the Middle East due to rising tensions in the region.
• In response to the assassination of Hamas' former political chief Ismail Haniyeh in Tehran on July 31, Iran's leadership has pledged to retaliate against Israel.

The Pentagon announced that the U.S. is deploying additional troops and military equipment to the Middle East to enhance its ability to safeguard Israel.

Lloyd Austin, the U.S. Defense Secretary, reaffirmed the United States' dedication to safeguarding Israel and highlighted the enhancement of U.S. military strength and readiness in the Middle East in response to intensifying regional conflicts, according to a statement released Sunday by Maj. Gen. Pat Ryder, Pentagon Press Secretary.

The guided missile submarine and the carrier strike group equipped with F-35C fighter jets will be sent to the region, with an accelerated transit.

On Sunday, Austin spoke with Israel's Defense Minister Yoav Gallant about the recent killing of Hamas' former political chief Ismail Haniyeh in Tehran and the threat of retaliation from Iran's leadership.

Hamas is backed by Iran, and Israel has not commented on the assassination.

The response of Tehran to the act has not yet been military, leaving its adversaries and the wider region in suspense.
